When creating a custom food, is it possible to define servings in terms of liquid measurements (cup, fl oz, etc.) instead of grams? Cronometer allows me to create a Serving Size named "1 cup", but it still forces me to define that in terms of grams of the custom food in order to add additional serving sizes. If I'm adding a liquid, the nutrition label typically gives grams of fat, carbs and protein per cup or fl oz of liquid, meaning I would need to manually weigh the liquid to determine the number of grams if Cronometer is unable to allow me to specify servings in terms of liquid measurements.
Even better would be if Cronometer would automatically add a set of liquid measurements (cup, pint, tbsp, fl oz, etc.) after the user had specified nutrition data for one of them, as the relationship between these units is fixed.
